Description
Technical field
The disclosure relates in general to a kind of impeller housing, and it is in bent portion and the part extended radially outwardly from bent portion
Between there is thickening formula linking part, impeller blade is attached to the bent portion.The disclosure further relates to a kind of above-mentioned impeller of manufacture
Method.
Background technology
Fig. 9 is the sectional view of a part for prior art impeller housing.Impeller housing 300 includes bent portion 302 and big
Cause is orthogonal to the rotation axis AR of housing radial component 304.Projection 306 due to punch-out 302 to form groove 308 and shape
Into the groove 308 is used to receive boss (not shown), to make impeller blade be fixed to housing 300.For by metal plate such as
The housing 300 manufactured by punching press and coining operation, in addition at projection, such as projection 306, housing 300 has nominal thick
Spend T1.Linking part 308 is subjected to extreme stress in the course of work of the torque converter including housing 300.However, housing 300
Thickness T2 at linking part 308 is only nominally more than T1, so as to undesirably reduce housing 300 and including housing 300
The stability and service life of torque converter.
Figure 10 A and 10B are the sectional views for the prior art process that impeller housing 300 is manufactured by metallic plate.The plate is placed in
In space 310 between mould 312,314,316 and 318, and compressed between mould, to obtain the shape shown in Fig. 9.Mould
Tool 312 includes recess 320, and it is arranged to be used to receive projection 306 in the forming process of housing 300, without flattening the projection.
Mould 312 includes recess 322, and it is arranged to be used to receive the projection on housing 300 in the forming process of housing 300, without
Flatten the projection.Mould 318 includes recess 324, and it is arranged to be used to receive housing 300 in the forming process of housing 300
Projection, without flattening the projection.
Line 11-11s of the Figure 11 along Figure 10 B sectional view.In recess 320 (shown in Figure 10), 322 and 324 it is each into
The form of corresponding continuous groove, to cause mould 312 and 318 and dashing forward for being aligned in projection 306 and housing 300 with 308 and 310
Play engagement and disengage.That is, the curved shape of mould 312 and 318 allows for shifting along direction Dl and D2, prominent without colliding
On rising.
The compression stress that is put on by mould 312 and 316 in a part for the metallic plate in the 310A of space is so that the part
Material flows towards space 310B, and linking part 308 will be located in the 310B of space.However, the compression stress between mould 312 and 314
It is not enough to prevent the major part of fluent material by space 310B and goes successively to space 310C.Therefore, linking part 308 is only mark
Ground is claimed to thicken.Especially, the dotted line in Figure 11 represents the metallic plate with projection 306.Space 326 corresponding projection 306 it
Between reserve.Mould 318 does not flatten (the substantially phase before and after being compressed by mould 312 and 314 of distance 328 of projection 306
Together)；Therefore, little or no compression stress puts on plate at the region in the space in corresponding to groove, so that material stream
It is dynamic to pass through linking part 308 and entering part 302.

Fig. 4-7B show a kind of exemplary method for manufacturing the impeller housing with thickening formula linking part.Although in order to clear
For the sake of and this method is presented with the sequence of step, but unless clearly stated, otherwise order should not be drawn with the sequence.With
Lower content should refer to from the point of view of Fig. 2-7B.First step：Use the recess in the multiple projections 200 and mould 208 on mould 202
206, projection 212,214 and 130 is formed on the side 116 of the metallic plate 216 with thickness 124.Second step：In projection
212nd, groove 162,164 and 166 is respectively formed in 214 and 130.Be described below, plate 216 be placed in mould 222,224,
226th, in the space 220 between 228 and 230.
Third step, in the part 220A in space 220,：By the part 222A of mould 222 formed it is smooth and continuous
Curved shape 232；With the smooth and continuous curved shape 234 that is formed by the part 224A towards side 116 of mould 224 it
Between, the Part I of grip block 216, the Part I corresponds to part 122 and including groove 162 and projection 212.Four steps：
In the part 220B in space 220, on the surface 236 formed by the part 222B of mould 222 and the surface formed by mould 226
The first end part of compression plate 216 between 238.
5th step：The material of the plate 216 in the Part I of plate 216 is set to correspond to linking part 132 towards space 220
Part 220C flowing.6th step：The material in the 220C of part is prevented to flow to the Part I (space 220A) of plate 216.
7th step：Thickness of the plate 216 in the 220C of part is set to increase to thickness 134, the thickness 134 is more than thickness 124.8th step
Suddenly：Produce thickness 136.
The Part I of grip block 216 includes：Projection 212 is flattened at least in part, to form projection 126.Show at one
In example property embodiment, the Part I of plate 216 includes projection 214, and the Part I of grip block 216 includes：At least in part
Projection 214 is flattened, to form projection 128.In one exemplary embodiment, the 9th step：In the part 224B by mould 224
The smooth and continuous curved shape 240 formed；Between smooth curved shape 242, the Part III of grip block 214, institute
State at least one recess 244 that smooth curved shape 242 is formed by the part 228A of mould 228 and is aligned with projection 130
Interrupt.The Part III of grip block 216 includes：Projection 130 is received in recess 244, and does not flatten projection 130 substantially.
In one exemplary embodiment, the tenth step：In the part 220D in space 220, respectively by part 228B
The Part IV corresponding to part 142 of compression plate 214 between the surface 246 and 248 that correspondingly forms of mould 230.One
In individual exemplary embodiment, surface 248 is a part for mould 224.
Advantageously, the above method adds the thickness and intensity of linking part 132.In particular, above-mentioned 6th step is prevented
Material flows to part 122 from linking part 132, and above-mentioned 7th step increases to thickness of the housing 100 at linking part 132
Thickness 134.
Fig. 8 A are the sectional views along Fig. 7 line 8-8, and it illustrates before being compressed between mould 222 and 224
Projection 212.
Fig. 8 B are the sectional views along Fig. 7 line 8-8, and it illustrates by compressing projection 126 formed by projection 212.
Herein below should refer to from the point of view of Fig. 2-8B.Dotted line display plate 216 in Fig. 8 A and Fig. 8 B.Prevention function in 6th step passes through
The smooth and continuous shape 232 that is formed by the part 222A of mould 222 is realized.As described above, mould 222 must be configured to
Mould 222 is set to be moved along direction Dl and D2, without colliding projection 212.Unlike the prior art, shape 232 is not
It is configured for reception projection 212, while only applying nominal pressure.On the contrary, the shallow profile of shape 232 causes sizable pressure
It is applied in projection 212.
For example, in Fig. 8 A, produce and contact between plate 216 and mould 222, but compression stress is not applied in projection 212.
Adjacent projection 212 is spaced apart in space 252 with distance 250.In one exemplary embodiment, 212 extend from part 122
One distance 144.As shown in Figure 8 B, distance 250 and space 252 significantly subtract after being compressed between mould 222 and 224
It is small.Space 252 reduces material the area that 122A passes through can be flowed to from part 132, thus as described above plus
Thick part 132.That is, plate 216 is compressed in the region under projection 126, so as to prevent or hamper material from linking part
132 flow to part 122.
It should be appreciated that the mould shown in Fig. 7 A and Fig. 7 B can be configured differently, while remaining to provide surface as described above
And shape.For example：Mould 222 and 228 is combined into single mould；And mould 224 and 226 is combined into single mould.
It should be noted that above-mentioned and other feature and function or its equivalent substitute can be desirably combined into it is many other different
System or purposes.Wherein, alternative solution, modification, modification or improvement various not expecting at present or do not expect hereafter will be by these
Art personnel make, so as to be also intended to be covered by claim.
